__init__(self, parent, id=ID_ANY, pos=DefaultPosition, size=DefaultSize, style=0, name="PieCtrl")

Default class constructor.

Parameters:

• parent – the PieCtrl parent. Must not be None;
• id – window identifier. A value of -1 indicates a default value;
• pos – the control position. A value of (-1, -1) indicates a default position, chosen by either the windowing system or wxPython, depending on platform;
• size – the control size. A value of (-1, -1) indicates a default size, chosen by either the windowing system or wxPython, depending on platform;
• style – the window style (unused);
• name – the window name.
